SIBIONICS GS1 warm-up: how long it takes

Warm-up takes 1 hour, with a countdown on screen. There are no readings and no alarms until it ends. (SIBIONICS user guide, p. 25; SIBIONICS user guide, p. 26)

What the maker says to do

1. Pair the sensor by scanning its QR code or typing the 8-digit code.
2. Wait 1 hour for the countdown to end.

The GS1 is not FDA-cleared and is not sold in the US; these answers come from SIBIONICS's EU/UK English user guide, its sibionicscgm.com pages and the UK App Store.
